Why is blender crashing when trying to render?
Similar questions are asked regularly in this site, and the answer is mostly the same: the scene's complexity is larger than the resources available on your computer.

Some of the reasons your scene demands so much RAM:


You are using a lot of very large image textures (2x and 3k). Even though you are using jpg compressed images that might not seem like large files, blender needs to access the image as a whole decompressed image. The larger the image, the more RAM used.

Some of the subsurf modifiers have a subdivision level of 5 for rendering. For every level of subdivision you are increasing the number of vertices exponentially, so it  is easy to run into a situation where you have a very large number of vertices. 

Try to keep the subsurf levels as low as you can by using better topology and using fine detail only in those areas that need a lot of detail.

You have 3 different render layers that you want to render simultaneously. Blender has to cache the information of every layer separately and keep it available for compositing.

A workaround is to render each of the layers separately, save it as an EXR file and combine them later in the compositor or other compositing app.

As is, your scene needs at least 1gb of ram to render:



2 or 3GB is very little RAM. Most of that is used by the operating system itself, leaving you very little to work with. Microsoft's requirements to run WIndows 10 are: 1 gigabyte (GB) (for the 32-bit version) or 2 GB ( for the 64-bit version)

To deal with scenes that are larger than your available computing power consider using a render farm or try to get access to more powerful computers. 

A (slow) alternative is to try to change the settings of your operating system to use more virtual memory. But that you will have to research yourself as it is out of the scope of this site.
